	\paragraph{Syntax}

\begin{verbatim}
X = expsmooth(X,Beta,...)
\end{verbatim}

\paragraph{Input arguments}

\begin{itemize}
\item
  \texttt{X} {[} tseries {]} - Input time series.
\item
  \texttt{Beta} {[} numeric {]} - Exponential factor.
\end{itemize}

\paragraph{Output arguments}

\begin{itemize}
\tightlist
\item
  \texttt{X} {[} tseries {]} - Exponentially smoothed series.
\end{itemize}

\paragraph{Options}

\begin{itemize}
\item
  \texttt{\textquotesingle{}init=\textquotesingle{}} {[} numeric
  \textbar{} \emph{\texttt{NaN}} {]} - Add this value before the first
  observation to initialise the smoothing.
\item
  \texttt{\textquotesingle{}log=\textquotesingle{}} {[} \texttt{true}
  \textbar{} \emph{\texttt{false}} {]} - Logarithmise the data before
  filtering, de-logarithmise afterwards.
\end{itemize}
